The equations of linear system are $\"\"$ .

The equations $\"\"$ of graph in coordinate plane is

$\"graph$

Observe the graph, the lines appear to intersect at the point $\"\"$ . $\"\"$

To check the ordered pair $\"\"$ is a solution of linear system, substitute $\"\"$ for x and $\"\"$ for y in each of the original equations.

Substitute $\"\"$ for x and $\"\"$ for y in the equation 1: $\"\"$ .

$\"\"$

$\"\"$ .

The above statement is true, so $\"\"$ is a solution of equation 1. $\"\"$

Substitute $\"\"$ for x and $\"\"$ for y in the equation 2: $\"\"$ .

$\"\"$

$\"\"$ $\"\"$

$\"\"$ .

The above statement is true, so $\"\"$ is a solution of equation 2.

Because $\"\"$ is a solution of each equation, it is a solution of the linear system. $\"\"$

The solution of the linear system is $\"\"$ .
